IMPROVEMENT IN STEAM-LUBRICATORS.

Specification forming part of Letters Patent No. 182,980, dated October3, 1876; application filed July ze, 181e.

To all whom it may concern Be it known that I, FREDERICK G.WIsE LOGEL,of Chicago, in the county of Cook and State of Illinois, have invented anew and useful Improvement in Steam-Lubricators, which is fullydescribed in the following specication, reference being had to theaccompanying drawings, in which- Figure 1 represents a front elevationof my iubricator; Fig. 2, a vertical section of Fig. l, taken on theline c c, Fig. 3'; Fig. 3, a plan view of the bottom of the lubricator;Fig. 4, a vertical section taken on the lineman,l Fig. l; Fig. 5, across-section taken on the line y y, Fig. l 5 Fig. 6, a perspective viewof the checkvalve, connecting the steam-passage into the oil-chamber;and Figs. 7 and 8, plan and sectional views of the screw-cock at thelower end of the gage.

My invention relates to a device for lubricating the interior otcylinders, governors, &c., when the oil is carried in with the steam.

The invention consists in the peculiar arrangement of the lubricatorupon the steampipe, so that the' opening of the steam inletpipe will beturned in the direction of said current, and also in providing the steaminletpipe with a check-valve, which closes the opening in the pipewhenever the pressure ofthe steam is removed.

In the drawings, A represents the oil cup or reservoir, which is ofordinary construction, and is provided with a stem, a, at its lower end,uponthe extremity of which a screwthread is cut. At the lower end of thestem a two pipes or tubes, B and C, are attached, the ends of which arebent outward in opposite directions, so that the mouths of the two pipeswill stand opposite each other.. The pipe B is intended to admit steamto the bottom of the oil-chamber, and communicates with a passage, b,extending up through the stem c, and opening directly into the bottom ofthe oil-chamber A. The pipe C is intended for the outlet-pipe, throughwhich the lubricating material escapes, and communicates with a passage,c, which also extends up through the stem c, and is prolonged by a tube,D, in the interior of the oil-chamber, which is attached to the stem c,and extends nearly to the top of the oil-reservoir A, as

shown in Fig. 2 of the drawings. A checkvalve, E, is placed in the upperend of the passage b. This valve I prefer to make of the form shown inFig. 6 ot the drawings. It sets loosely in the upper end of the duct orpassage b, to which it is tted, and is prevented t'rom rising entirelyout of its seat by a loop, e, fastened to the stem a, and extending overthe top of the valve at such a distance above it as to permit it to beraised sut'- ciently to admit steam into the chamber A. The duct orpassage b is fitted with a valve, F, by means of which the size of theopenings may be regulated at pleasure. Asimilar val ve, G, is fitted inthe duct c for a similar purpose.

An ordinary gage, H, is attached to the lubricator, which communicateswith the oilchamber A, both at thetop and bottom, by passages h li', asshown in Fig. 4 of the drawings. This operates in the usual manner toindicate the amount of lubricating tiuid in the chamber A.

The passages h h are controlled by suitable valves I and J, and byopening the lower passage and turning a cock, K, in the bottom of thegage-tube, the lubricating fluid may be drawn oft' from the chamber A.

From the above description it is evident that if live steam is admittedto the chamber A through the pipe B and duct b, the pressure of thesteam will force the lubricating material out through the tube D,passage or duct c, and pipe C.

To secure this operation I attach the lubricator to the steam-pipe byscrewing the lower end of the stem into a suitable hole in the pipe, asshown in Fig. 2 of the drawings, in which L represents a section of asteampipe. Y

The arrow below, Fig. 2 of the drawings, indicates the direction of thesteam in the steam-pipe, and the lubricator should be arranged as shownin this figure, with the mouth of' the pipe B turned toward the currentof steam, while the pipe C is turned in the opposite direction. Theducts b and c being opened by turning the valves F and Gr, the steamwill be forced into the pipe B, up the duct b, and raising thecheck-valve E, will enter the chamber A. The pressure of the steam isthus brought within the chamber A, and, acting upon the lubricatingl'luid, will force it out through the pipe C, as above described, Whereit is taken up by the passing current ofsteam, and carried into thecylinder or governor.

As soon as the steam is shut cti', or its pressure is for any reasongreatly diminished, the check valve E will immediately drop into itsseat, and prevent the escape of any oil through the passage b. Thepressure of the steam in the oil-chamber, and the amount ot' lubricatingmaterial owing out through the passage c, are regulated to a nicety bymeans of the valves F and G.

The lubricator should be set in the steampipe as near as possible to thecylinder, governor, or other device to which steam is admitted, andwhich it is desired to lubricate.

Having thus described my invention, what I claim as new, and desire to`secure by Letters Patent, is

1. .The combination of the steam-pipe L and the lubricator A,constructed with a short steam-duct, b, and a long oil-duct, c D, andbent pipes B and C at the bottom of the stem, and arranged in thesteam-pipe so that the pipe B will open toward the current of steam, andthe pipe G from said current, substantially as and for the purpose setforth.

2. The combination of the oi1-chamber A, passages or ducts b c in thestem a, tube D, bent pipes B C, and check-valve E, substantially as andfor the purpose set forth.
